    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    Collaborative Research and Rate of Interests

    Full text link
    This paper makes an attempt to link collaborative research in industry with Government initiative and market rate of interests. Two firms involved in Cournot competition in the market are deciding whether to conduct research to device a technique for cost reduction. Amount of cost reduction after the research and the initial amount of capital possessed by each firm are private information to each of the firms. In particular both of them are having capacity constraint. Our objective here is to figure out the impacts of the lending and borrowing rates of interest on collaborative research. In the process we study the effectiveness of different policies to encourage collaborative R&D

    Selling a Cost Reducing Production Technique through Auction in a Duopolistic Industry

    Full text link
    This paper considers a two-stage game, where in the first stage, two firms bid non-cooperatively for a production technique that leads to a reduction in cost. Following the auction in the second stage of the game these firms compete against each other in a duopolistic industry. The amount of cost reduction for every firm following the adoption of the production technique is a private information to the concerned firm. In the model, the auctioneer is the government. Before the auction, the government announces whether she will reveal the bids after the auction, which is her choice variable. This paper makes an attempt to figure out the welfare implications of the bid disclosure policies under different parametric and market conditions. Our findings suggest that for the Bertrand competition in the second stage the revelation of the bids does not have any impact on the level of social welfare. For the Cournot competition in the second stage, whether the disclosure of bids would lead to higher level of social welfare than when the bids are suppressed, is determined by parametric conditions

    Cooperative vs. Non-cooperative R&D under Uncertain Probability of Success

    R&D decision of a firm involves various sources of incomplete information. The present paper introduces incomplete information about the success probability of R&D in a model of two firms interacting in R&D and production and discusses the choice between cooperative and non-cooperative research. We consider research joint venture as the form of R&D cooperation. While the choice depends on the constellation of parameters, the following results are derived, in general. First, the high type firm always has a larger incentive for both cooperative and non-cooperative R&D compared to the low type firm. Second, if the low type firm goes for non-cooperative research, then the high type firm must go for the same, and if the high type firm prefers cooperative research, the low type firm must also prefer cooperative R&D. However, if the high type firm prefers non-cooperative R&D, the low type firm may go for either form of research depending on the parameters. The paper derives conditions, in particular, for the case when the high type firm prefers non-cooperative research whereas the low type firm prefers cooperative research
